10 Claims.

The main objects of this invention are:

First, to provide a temporary binder or loose sheet holder oftheclampingbar post type in which the sheet body may be opened foreffective use and at the same time has a relatively small amount ofbinding margin.

Second, to provide a temporary binder or loose sheet holder having theseadvantages in which the sheet body is very securely held even in bind-:ers of large dimensions and a thick sheet body.

Third, to provide a temporary binder or loose sheet holder which isadapted for sheets originallyintended for the post type of binders.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embod illustrated in the a 'which:

Fig. 10 is a perspective view of one of the amping bar hinge plates ormembers. In the embodiment of my invention illustrated, the covers I and2 are of suitable structure and dimensions to accommodate the sheet bodyconventionally shown at 3. The clamping bars des .ignated by the numeral4, in the preferred embodiment illustrated, comprise the outernonmetallic relatively thick elements 5 and the inner metal plates 6,the elements being secured together by the screws 21.

The outer binder bar elements 5 have slotiment of the invention isccompanying drawings, in

on on line 4-4 of Fig. 3. section on line 4-A 4-A The purpose of 1938,Serial No. 186,652 (01. 1291) like recesses 8 extending from their inneredges, the rear ends of the slots being adjacent the rear edges of theelements 5 as shown in Fig. 3.

The plates 6 have slots 7 opening to the recesses 8, these slots beingarranged quite close 5 to the rear edges of the plate 6 or, in otherwords, quite close to the rear edges of the clamping bars.

this will appear as the description proceeds. The plates 6 extend acrossthe recesses closing their inner sides and also rein- 10 forcing theelements 5 so that the completed clamping bar has the desired strengthand rigidity.

The clamping bars are provided with hinge plates 9, those illustratedbeing of channel section andsecured to the plate 6 in an outwardlyfacing relation within the recesses by spot-welding at 29.

The covers are provided with arm-like hinge members l8 preferably ofchannel cross section disposed with the channels facing inwardly andwith the flanges thereof pivoted to the flanges of the hinge plate bymeans of the pivots II. It will be noted that these pivots are locatedwell to the rear of the center of the clamping bars but somewhat inadvance of the slots lsee Fig. 3.

The hinge members ID are preferably inwardly offset at l2 so that theymay be secured on the inner sides of the covers and the outer sides oftheir projecting portions are approximately flush with the outer sidesof the covers and with the clamping bars when the parts are in closedposition.

The flexible binding members l3 are secured at one end to the cover I asby means of the rivets Hi, their other ends being secured to theadjusting member l5 carried by the cover 2. As the details of theadjusting means form no part of this invention they are not furtherdescribed herein. It will be noted by reference to Fig. 3 that thesebinding members are disposed longitudinally within the hinge members into pass through the slots 7 in the faces of the clamping bars and thatthe reaches thereof extending between the clamping bars lie at the rearof the rear edges or end of the sheet body 3 as distinguished from beingengaged within slots of the binding member receiving openings in thesheets. 50

The clamping bars are provided with sockets l5 positioned to receive thepins I1 on the post bars i8. These post bars are provided withnonaligned posts l9 engageable with holes 20 provided therefor in thesheets. In the embodiment illustrated, the pins H are located welltoward the edges of the post bars, a part of them, the outer pins in theembodiment illustrated, being closely adjacent the front edges of thepost bars and the center or intermediate pin being closely adjacent tothe rear edges of the post bars.

The posts 59 are closely adjacent the front or inner edges of the postbars as best shown in Fig. 2, and it will also be noted that the postbars and the entire sheet body lie in front of the reaches of thebinding members extending between the clamping bars. By this staggeredrelation of the pins or studs H on the post bars, the tendency of thepost bars to rock on the clamping bars is minimized or, in other words,their engagement is stabilized against the various stresses to whichthey are subject in the manipulation of the binder.

The position of the binding members. relative to the post bars and tothe clamping bars further results in holding the parts in positionnotwithstanding the relatively narrow binding margin of the sheets.

To urge the inner edges of the post bars inwardly upon the sheets, thewebs of the hinge plates Q are provided with supports 2! for the bindingmembers, see Fig. 3, these supports being in the form of outwardlydisposed bead-like rolls on the front edges of the web portions of thehinge members 9, see Fig. 3.

This arrangement of parts insures a clamping stress of the bindingmembers upon the inner edges of the clamping bars when the binder isclosed and further stabilizes the clamping bars and post bars in theirrelation the one to the other.

In Fig. 8, I illustrate an embodiment in which the post bars areprovided with telescoping post members 22 and 23.

My improved binder is adapted for receiving sheets designed for postbinders of various types, it only being necessary to space the posts tocorrespond to the spacing of the holes 20 in the sheets. The sheets areeffectively bound by a relatively narrow binding margin which of courseis a desirable factor as a larger proportion of the sheets may beutilized for recording purposes or the sheets may be of less length forthe same amount of writing surface as compared to the average postbinder or binder of this general type now on the market.

I have illustrated and described my improvements in highly practicalembodiments thereof.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
